Compilation error

[Abdeslam Houari]

Dear Exciting Users and Developers;
I'm a young researcher from university of Bejaia, Algeria.
I'm activating in computational solid state physics, using DFT-based methods and codes. I'm very interested in FP-LAPW method and Exciting code.
I have download the last release exciting lithium.
I'm working under 64-bits Debian-Linux PC with gfortran compiler and when I try to compile it (typing make and choosing the suitable details) I get the following error:

../../src/mod_potential_and_density.F90:11.18:
      Use modinput
                 1
Fatal Error: Can't open module file 'modinput.mod' for reading at (1): No such file or directory
make[3]: *** [mod_potential_and_density.o] Error 1
make[3]: Leaving directory `/home/abdeslam/exciting/Lithium/build/serial'
make[2]: *** [bin] Error 2

It seems that some module (modinput.mod) is missing. I don't know where to find it and how to fix this? What should I do to compile it correctly?
I would be very grateful for a help... Thank you so much in advance.

Best regards
